ITHUEL M. JOHNSON, OF GORNING, NEW YORK.

WAGON-JACK.

SPECIFICATION forming part of Letters Patent No. 276,594, dated May 1,1883. Application filed March 13,1883. (No model.) I

To all whom it may concern:

Be it known that I, ITHUEL M. JOHNSON, a citizen of the United States ofAmerica, residing at Corning, in the county of Steuben and State of NewYork, have invented certain new and useful Improvements in Wagon-Jacks,of

which the following is a specification, reference being bad therein tothe accompanying drawings.

This invention relates to improvements in combined lifting-jack andwrench; and it consists in the combination and construction of parts,substantially as hereinafter more fully set forth.

In the accompanying drawings, Figure 1 is a side elevation of myimproved lifting-jack. Fig. 2 is a perspective folded view thereof. Fig.3 is a detailed view of the same, asis also Fig. 4, embodying thewrench.

In carrying out my invention I employ two upright pieces, A, pivotedtogether by the pivot-bolt A at their upper ends, and adapted to bespread apart at their lower ends, it thus being caused 'to assume an Ashape. The lower ends of these uprights are each provided with a pointedprojection, a, and alateral projection, a, the former being adapted topenetrate the ground and prevent the slipping of thejack and the latterto prevent the sinking of the. standards thereinto, while, when thejack, is used indoors, cushions or disks a-, of rubber, are applied tosaid point-projections to prevent the warring of the floor.

B is the lifting bar or lever, pivoted between the upper ends of theuprights A A, and preferably by the same pivot-bolt used to connect thelatter together. The forward slightly hooked end of the lever B, by theaction of which the weight or the axle of the vehicle is lifted, issupplied with a rubber band or cushion, b, to avoid defacingnicely-painted axles. This lever and one of the uprights A-the frontone-are provided with notches, as at c, with which is adapted to engagea bail, U,im' provised into a wrench, O. The bail O has at its upperend, on each side,a hook, 0 adapted to engage with the notches of thelever. I By exerting downward pressure upon the longer arm of the leverB and slipping the hook at the upper end of the bail into the desirednotch of the lever and the lower end thereof into the required notch ofthe front bar, A, the lever, with its supported axle or weight, willwrench.

When the parts are folded, as shown in Fig 2, it will be noticed thatthe bail O is slipped upon and buttoned to one of the bars A by means ofa button-shaped head, 6, on one end of the pivot-bolt A, it beingadapted to permit the insertion of the bail between said head or buttonand the bar A, said button being adapted to be turned so as to securethe bail to the bar. The pin or projection d of the wrench or bail isinserted through the notch f in the edge of one of the bars A and entersa depression or indenture, g, in the other bar A, aiding the securing ofthe parts compactly together.

Iclaim and desire to secure by Letters Pat ent-- 1. In a lifting-jack,the combination, with the pivoted-together bars, one being notched, ofthe notched lever, and the bail having a lateral hook at its upper orone end and on one or both sides, substantially as and for the purposeset forth.

2. In a lifting-jack, the bars having their lower ends provided eachwith a pointed projection and a lateral projection, substantially" asand fort-he purpose set forth.

3. In a lifting-jack, the bars A, having their pivot-bolt provided witha buttonshaped head, 6, in combination with the bail 0, substantially asand for the purpose set forth.

4. In a lifting-jack, the bars A, with their pivot-bolt provided withabutton-shaped head, 6, one of said bars also having a notch,f, and

the other a recess, g, in combination with the bail 0, having thelateral pin or projection d, substantially as and for the purposespecified.

In testimony whereof I affix my signature in presence of two witnesses.

ITHUEL M. JOHNSON.
